A device and system for releasably securing a watchband to a watch casing. Specifically, a watchband connector pin is formed of a shape memory material, preferably a shape memory alloy. The watchband may be readily released and reattached from a watch casing to facilitate repairs of the watch, for aesthetic considerations, or when the watch band is damaged or worn. The connector pin is durable due to the one piece design, easy to operate, flexible, and economical to produce.

A wrist watch assembly, comprising: first and second connector pins, each connector pin having a first and a second pin end, each connector pin being formed of a single piece of shape memory metal alloy; first and second wristband straps, each of said wristband straps having a proximal end adapted for receiving a connector pin for connecting said wristband strap to a watch casing and a distal end for connecting said wristband strap to the other of said wristband straps; and a watch casing having a first and a second pair of connector pin receptacles defined therein for receiving the pin ends of said first and second connector pins, wherein said shape memory alloy has a shape memory effect which allows the alloy to return from a deformed shape to a preset shape after being heated above a transition temperature, said transition temperature being a temperature at which said shape memory alloy transforms from a martensitic state into an austenitic state.
